What Is a Tunnel Washer?

Tunnel cleaning machine is a device that sprays water mixed with detergent on the tunnel wall surface, underground lane wall surface and road signs and other operating surfaces during driving, and then cleans it with a cleaning brush. The tunnel cleaning machine is equipped with a cleaning brush on a 2-section folding arm jack that can be rotated left, right, up, down and 270 ° to clean the inside of the tunnel. It is quickly cleaned with a high-pressure water pump and equipped with a large-capacity water tank to improve operation effectiveness. The cleaning brush of the tunnel cleaning machine can be replaced and used according to the operating conditions.
